How to Scope a Roof for Supplement Before the Adjuster Arrives

Most supplements die before they are ever written. They die on the roof, during the first inspection, when the person walking the slopes treats the visit like a sales call instead of a scope. By the time the carrier's estimate comes back light and somebody on your team opens a supplement, the evidence that would have justified the extra money is already gone. The shingles got torn off. The decking got covered. The flashing went in the dumpster. Nobody photographed the rotted fascia before the gutter went back up.

Scoping a roof for supplement before the adjuster arrives is the single highest-leverage hour in the whole insurance restoration process. Do it well and the supplement practically writes itself, because every line item you eventually ask for is already documented, measured, and tied to a reason the carrier recognizes. Do it poorly and you spend the next ninety days emailing photos that prove nothing, arguing about quantities you guessed at, and eating costs you should have been paid for.

What follows is the actual field workflow practitioners use to scope a roof so the supplement is a formality, not a fight. It covers the measurements that matter, the line items adjusters routinely miss, the photo protocol that survives a desk review, the code references that turn a "maybe" into a "required," and the edge cases that trip up even experienced crews. None of it requires you to handle the claim, promise an outcome, or say anything about a deductible. Your job is to document conditions and produce an accurate estimate. The insurer decides coverage and the homeowner owns the claim. Everything here keeps you squarely inside that lane.

What a supplement actually is, and why scoping decides it

A supplement is a request to add or adjust line items on an insurance claim after the initial scope, because the original estimate did not capture the full, correct cost to restore the property to pre-loss condition. It is not a markup, not a padding exercise, and not a negotiation tactic. A clean supplement is simply the difference between what the property actually requires and what the first estimate accounted for.

That difference comes from a handful of predictable sources:

• Quantity errors. The carrier's estimate used the wrong squares, the wrong waste factor, or undercounted pitch and complexity.
• Missing line items. Drip edge, starter, ridge cap as a separate item, ice-and-water barrier, step flashing, ventilation, detach-and-reset of solar or satellite, the list goes on.
• Unforeseen conditions. Rotted decking, layered roofs, deteriorated flashing that could not be assessed until tear-off.
• Code-required upgrades. Items the building code now mandates that the existing roof did not have, which are owed when the carrier's policy includes ordinance-or-law coverage.
• Access and labor realities. Steep, high, or cut-up roofs that change the labor rate or require equipment the base estimate ignored.

Here is the part that matters: every one of those categories is easiest to prove at the first inspection. Quantity errors are easiest to catch when you have your own measurements in hand before the adjuster shows up. Missing line items are obvious when you have walked the roof and built your own scope. Unforeseen conditions like rot can be flagged the moment you spot a soft deck or a sag. Code upgrades are knowable the day you identify the roof's age, the local code edition, and what is missing. Access realities are visible from the driveway.

The adjuster's visit is not the moment you discover these things. It is the moment you confirm what you already documented. That reframe is the whole game.

The mindset shift: scope first, sell second

The most common mistake is treating the pre-adjuster inspection as a closing appointment. The rep climbs up, finds enough hail hits to call it a claim, takes a few phone photos, comes down, and signs the homeowner. Functionally that works for getting the contract. It is a disaster for the supplement, because the rep never built a real scope.

A scope is a complete, quantified description of everything required to restore the roof, independent of what the carrier will eventually pay. You build it as if you were going to do the job on a cash basis and had to hand the customer an exact, defensible number. Only after that scope exists do you compare it against the carrier's estimate to find the gaps. The gaps are your supplement.

This is why the best restoration companies separate the roles. The salesperson signs the deal. A trained inspector or project manager builds the scope. Sometimes they are the same person, but the two jobs use different parts of the brain, and conflating them is how line items get lost. If you run a small shop and you are both, slow down and switch hats deliberately. Sign the customer, then go back up and scope like an estimator.

Step 1: Get accurate measurements before anyone else does

You cannot supplement a quantity you did not measure. The foundation of the entire scope is an accurate measurement report, and you want it in hand before the adjuster sets foot on the property. There are three ways to get it, and serious operators use a combination.

Aerial measurement reports

Services that generate roof measurements from aerial and satellite imagery give you total area, slope-by-slope breakdown, ridge and hip lengths, valley lengths, eave and rake lengths, and pitch. A good report is the spine of your scope because almost every line item is a function of one of those numbers. Starter is a function of eave plus rake. Ridge cap is a function of ridge plus hip. Ice-and-water is a function of eave length and code requirements. Drip edge is eave plus rake. If your measurement numbers are right, your quantities defend themselves.

Order the report early. The most common avoidable error is showing up to the adjuster meeting working off the carrier's squares because your own report was not ready. When you have an independent, third-party measurement document, a quantity dispute stops being your word against the adjuster's and becomes a comparison of two documents, which you usually win when yours is more detailed.

Hand measurements and verification

Aerial reports are excellent but not infallible. Heavy tree cover, very recent construction, additions not yet in the imagery, and complex architectural details can throw them off. Verify the spots that matter. Walk the perimeter and confirm eave and rake lengths roughly match. Check pitch with a pitch gauge or a level and tape on a representative slope. Note anything the aerial cannot see, like a lower porch roof tucked under a tree or a dormer cheek that imagery flattens.

When your hand check and the aerial report disagree by more than a few percent, figure out why before the meeting, not during it.

Pitch, stories, and access multipliers

Labor is not a flat rate. Steep and high roofs cost more to tear off and install, and most carrier estimating platforms have line items for exactly that. Document the pitch of every slope, rather than only the predominant one. A roof that is mostly 6/12 with a 10/12 front gable owes steep charges on that gable. Document the number of stories and any two-story or three-story sections, because high-roof and second-story labor modifiers are legitimate and routinely omitted from a base estimate.

Write all of this down in a structured way before the adjuster arrives. A measurement summary that lists area by slope, total squares with waste, pitch by slope, story height, and linear footage of every roof edge feature is the document that anchors the whole conversation.

Step 2: Build your own complete line-item scope

With measurements in hand, build the scope you would hand a cash customer. Go component by component. The goal is a list where every item has a quantity, a reason, and a photo or measurement backing it.

Here is the working component checklist a thorough inspector runs through. Treat it as the skeleton of your scope, and add anything specific to the property.

Notice that several of these items cannot be fully confirmed from the surface. Decking condition is the obvious one. You flag it now as a likely supplement and confirm it at tear-off, with photos. That is normal and expected. The point of the pre-adjuster scope is to identify every probable line item, document what you can see, and set up the items you will confirm later.

Quantities, not guesses

For each line item, write the actual quantity from your measurements, not a round number. "Drip edge, 312 LF" is defensible. "Drip edge, all around" is not. When the supplement goes in, specific quantities tied to your measurement report move fast through review. Vague quantities invite questions and delay.

Waste factors that hold up

Waste is a frequent dispute. The honest answer is that waste depends on roof complexity and shingle type. A simple gable roof with architectural shingles runs lower waste than a cut-up hip roof with multiple valleys. Use the waste factor your measurement report calculates from the actual geometry, and be ready to explain it. If you claim more waste than a simple roof would generate, the geometry has to justify it, and your slope diagram does exactly that.

Step 3: The photo protocol that survives a desk review

Most supplements are reviewed by a desk adjuster who never sees the property. Your photos are the property. If a condition is not photographed clearly, with context and scale, it does not exist as far as the review is concerned. A casual handful of phone shots does not cut it. You need a protocol.

Shoot in layers: overview, then detail, then proof

For every claimable condition, take three kinds of shots:

1. Overview. A wide shot showing where on the roof this is, so the reviewer can orient. The slope, the elevation, the general area.
2. Detail. A closer shot showing the condition itself clearly.
3. Proof. A tight shot with scale or markup. Chalk circles around hail hits, a tape measure across a quantity, a coin or chalk line for size reference on a bruise.

Three shots per condition feels like a lot until the first time a desk reviewer denies a line item because "the photo is inconclusive." Then it feels like cheap insurance.

Document slope by slope, with a test square

The industry-standard way to document hail is a 10-foot by 10-foot test square chalked on each slope, with the hits inside it marked and counted, plus a photo of the marked square and a note of the hit count. Do this on every slope, including the ones that do not look damaged, because directional storms hit slopes unevenly and the carrier's threshold is often a hit count per square per slope. A north slope with eight hits and a south slope with two is a real, common pattern, and you can only prove it if you documented both.

Photograph soft metals while you are up there. Gutters, downspouts, fascia wraps, vents, valleys, and any aluminum or low-gauge steel. Hail leaves dents in soft metals that corroborate roof damage and help establish the date and direction of the storm. Hit the gutter aprons, the AC condenser fins, the mailbox, the garage door, and any window screens. Collateral damage on the ground often makes the case for damage on the roof.

Capture the pre-loss and the hidden conditions

Before you touch anything, photograph the conditions you will later need to prove were already there or could not be seen. The fascia behind the gutter. The rake board. The underside of the deck in the attic if accessible, looking for daylight, staining, or prior leaks. Existing flashing condition. The number of roofing layers, visible at a cut edge or a rake. Layered roofs change the tear-off line item, and you want that photographed before the first shingle moves.

Metadata, sequence, and a shot list

Use a camera or app that timestamps and ideally geotags photos. Date and location metadata corroborate that the inspection happened when and where you say. Keep the photos in a logical sequence by slope and component, and keep a simple shot list so the same protocol runs on every roof regardless of who is on it. Consistency is what makes a desk reviewer trust the package.

A practical minimum shot list per inspection:

• Four elevations of the house from the ground
• Address marker or a distinguishing feature for identity
• One overview per slope
• One marked test square per slope with hit count
• Detail and proof shots of every claimable hit cluster
• Every penetration: pipes, vents, chimneys, skylights
• Every wall and headwall flashing condition
• All soft-metal collateral, roof and ground
• Layers visible at a cut edge
• Any sag, soft spot, or staining
• Attic interior if accessible

Build the photo set for the reviewer, not for yourself

The person who took the photos understands them. The desk reviewer three weeks later does not. Caption or sequence the set so a stranger can follow it without you in the room. A simple convention works: name or tag each photo with the slope and the component, so "north slope, test square, 9 hits" reads at a glance. When a reviewer can reconstruct the entire inspection from the photos alone, your supplement stops depending on a phone call to explain it. The package speaks for itself, which is the whole point of building one.

The mistake of the hero shot

Reps love the dramatic single photo of the worst damage on the roof. One spectacular hail bruise feels persuasive. It is not, by itself, a scope. A claim is built on the pattern across the whole roof, slope by slope, plus the collateral on the soft metals and the ground. The hero shot has its place inside a detail-and-proof sequence, but a folder of ten hero shots with no test squares, no slope coverage, and no collateral is a weak package dressed up as a strong one. Coverage beats drama. Document the boring slopes too.

Step 4: Tie conditions to code, beyond opinion

The strongest supplement line items are the ones backed by code, because code is not negotiable the way opinion is. When a carrier's policy includes ordinance-or-law coverage, code-required upgrades triggered by the repair are owed. Your job at the pre-adjuster scope is to know which code items apply to this roof and document why.

Know your edition and your local amendments

Building codes are adopted at the state and local level, and editions vary by jurisdiction. The International Residential Code is the base most places start from, but your county or city may be on a different edition or may have amendments. Before the meeting, know which code edition the local jurisdiction enforces and what it requires for a reroof. The items that most often become code-driven supplements:

• Ice barrier at eaves. In regions subject to ice, code requires an ice-and-water membrane extending a set distance up-slope past the interior wall line. If the existing roof does not have it and code requires it, that is a code item, not an upgrade.
• Drip edge. Modern code editions require drip edge at eaves and rakes. Older roofs often lack it. If the code in force requires it, reinstallation is owed.
• Underlayment type and attachment. Code may specify underlayment requirements that differ from what is on the roof.
• Decking attachment and condition. Re-nailing decking to current fastening schedules is required in some jurisdictions during a reroof. Damaged or non-conforming decking must be replaced to code.
• Ventilation. Code specifies minimum net free ventilation area. If the roof is under-ventilated, bringing it to code during the reroof can be required.
• High-wind and impact zones. Coastal and high-wind regions carry additional fastening, sealing, and product requirements.

Write the specific code section next to each code-driven line item in your scope. "Ice barrier required per [local code section], existing roof has none" is a sentence that ends an argument. Vague appeals to "code" without a citation get waved off.

Manufacturer requirements count too

Beyond municipal code, manufacturer installation instructions carry weight, especially where a warranty is in play. If the manufacturer requires a specific starter, a specific underlayment, or six nails per shingle in a wind zone, that requirement supports the corresponding line item. Keep the relevant installation instructions handy. They are public documents and they back your scope.

Step 5: Where RoofPredict fits in the pre-adjuster workflow

Everything to this point assumes you are already standing on the right roof. The harder problem upstream is knowing which roofs to be on, and being ready with the storm context before you ever climb. That is where RoofPredict fits, and it is worth being precise about what it does and does not do.

RoofPredict tells roofing contractors which roofs in an area are due, house by house. For each address it produces a roof-age range estimated from aerial imagery, and it models storm physics per individual roof rather than treating a whole zip code as one event. The output is a ranked list of doors and routes so your crews knock the roofs a storm actually wore out, plus the roofs that are simply aging out of their service life.

In a pre-adjuster scoping context, two pieces of that are directly useful.

First, the roof-age range. Roof age is a major driver of what your scope will look like. An older roof is more likely to lack drip edge, to be under-ventilated, to have brittle decking, and to be missing the code items modern editions require. Walking up already knowing the age range tells you which code-driven line items to look for. It is a range, not a manufacture date, and you confirm the actual condition on the roof. But starting with "this roof is probably in its later years" focuses your inspection on the items most likely to support a supplement.

Second, the per-roof storm modeling. Knowing the modeled hail or wind exposure for the specific address before you arrive tells you which slopes to scrutinize and which storm date to reference. A model is odds, not proof. It does not substitute for the test squares you chalk on the roof, and you should never present a model as evidence of damage. What it does is point you at the slopes most likely to carry the damage, so your physical documentation is thorough where it counts. The chalk square on the roof is the proof. The model just told you where to chalk first.

The honest limits matter. RoofPredict does not inspect the roof for you, does not measure your line items, does not document conditions, and does not have any role in whether a claim is covered. It ranks which roofs are worth your time and gives you context to inspect smarter. The scope, the photos, the measurements, and the code citations are still your work, done on the roof, the way the rest of this lays out. Used that way, it shortens the distance between "which roofs are due" and "this roof is fully documented before the adjuster arrives."

How to handle the adjuster meeting itself

The pre-adjuster scope pays off in the meeting, so handle the meeting well. Be on the roof with the adjuster, not in the driveway. Bring your package in printed or tablet form. Walk the roof together and let the documentation lead. When you point at a condition, you are confirming a photo and a measurement you already have, which builds trust fast.

A few practical habits separate a smooth meeting from a contentious one:

• Lead with measurements, not opinions. Open with the area and slope numbers from your report. Establishing agreement on quantities early removes the biggest source of friction before damage is even discussed.
• Walk every slope. Show the test squares you chalked on each one. An adjuster who sees you documented the clean slopes too tends to trust your damaged-slope documentation more.
• Name the code items plainly. Point at the missing drip edge or absent ice barrier and state the code section. Let the citation do the work.
• Flag the tear-off items out loud. Say which conditions you expect to confirm at tear-off so the later supplement is no surprise.
• Stay in your lane. Discuss conditions and the cost to restore correctly. Leave coverage decisions to the adjuster and the carrier.

If the adjuster disagrees on an item, do not argue it on the roof. Note the disagreement, keep your documentation, and address it through the proper supplement and reinspection process with the evidence in hand. A calm, documented contractor is far more persuasive than a loud one, and the relationship you build across multiple claims with the same carrier compounds.

When a reinspection is the right call

Sometimes the first adjuster scope misses items you documented and the desk will not move on paper alone. A reinspection, where a second adjuster or a ladder assist revisits the roof, exists for exactly this. Request it when your documentation clearly supports items the first scope denied, and bring the same disciplined package. Because you scoped thoroughly the first time, a reinspection is a chance to confirm what you already proved, not a scramble to find new evidence. Contractors who skip the upfront scope dread reinspections; contractors who scoped properly welcome them.

Step 6: Assemble the pre-adjuster package

Before the adjuster meeting, assemble everything into a single package you can hand over or walk through. A loose pile of photos and a verbal pitch is weak. A clean package signals you are organized, which changes how the adjuster engages with you.

The package contains:

1. Measurement report. The third-party aerial report plus your verification notes.
2. Line-item scope. Your complete component list with quantities, in the same general format the carrier's estimating platform uses if you can manage it. Speaking the platform's language reduces friction.
3. Photo set. Organized by slope and component, with the test squares and hit counts visible.
4. Code references. The specific sections for every code-driven item, with a one-line note on why each applies.
5. Conditions to confirm at tear-off. A short list of items, like decking and hidden flashing, that you are flagging now and will document with photos when the roof opens up. Setting this expectation up front makes the eventual decking supplement routine instead of a surprise.

That last item is underused and powerful. Telling the adjuster at the first meeting "we will likely find decking damage under the felt and will document it at tear-off" pre-frames the supplement. When it comes in three weeks later with photos, it is the confirmation of something already discussed, not a new ask out of nowhere.

A worked example: 28-square hip roof, recent hail

Make this concrete. A two-story home, 28 squares of architectural shingle, predominantly hip with several valleys, a 7/12 main pitch with a 10/12 entry gable, gutters on all eaves, one chimney, two plumbing stacks, a kitchen vent, and a satellite dish. Recent hail event. Carrier's initial estimate came in at 24 squares, minimal accessories, no steep charges, no code items.

Here is how the pre-adjuster scope catches the gaps.

Squares. Your measurement report shows 28.4 squares of actual area. With the hip-and-valley complexity, the report calculates a waste factor that brings the order quantity higher than the carrier's flat number. The carrier's 24 squares is simply wrong on geometry. Gap identified, document-versus-document.

Steep and high charges. The 10/12 entry gable owes steep labor on its area. The whole roof is two stories, owing high-roof labor. The base estimate has neither. Gap identified, with pitch and story documentation.

Accessories. The carrier bundled starter and ridge cap into field shingles. Your scope breaks out starter at eave-plus-rake LF, ridge-and-hip cap at the measured LF, drip edge at eave-plus-rake LF, and valley metal at the valley LF. Four line items the base estimate folded away or skipped.

Flashing and penetrations. Step flashing along the chimney sides, apron at the chimney front, counter flashing reset, two pipe boots, and a kitchen vent. The base estimate assumed reuse. Your photos show deteriorated step flashing and brittle boots. Gap identified with proof shots.

Detach and reset. The satellite dish needs detach and reset. Not in the base estimate. One line item, photographed.

Code items. The home is in a jurisdiction whose code requires drip edge at all edges and an ice barrier at eaves. The existing roof has neither. With ordinance-or-law coverage in play, both are code-driven line items, each with its code section cited in your package.

Flagged for tear-off. From the attic you spotted staining near the chimney and one soft area underfoot on the north slope. You note decking replacement as a probable supplement to confirm at tear-off, and you photograph the attic staining now.

None of this is padding. Every line item is a real cost to restore the roof correctly, every quantity is measured, and every condition is photographed or flagged. When the supplement goes in, it is a structured comparison between your documented scope and the carrier's light estimate. That is a supplement that gets approved on its merits rather than ground down in back-and-forth.

Putting numbers to the gap

It helps to see the gap as a table, because that is exactly how it reads when the supplement lands on a reviewer's desk. The point is not the specific dollars, which vary by region and pricing database, but the structure: every row is a documented quantity the base estimate either undercounted or skipped.

When the supplement is laid out this way, the reviewer is not reading an argument. They are reading a reconciliation. Each row points to a document or a photo that already exists. Reviewers approve reconciliations far faster than they approve arguments, because there is nothing to dispute except the documents themselves, and the documents are sound.

Why the order of operations matters

Notice the sequence that made this possible. The measurement report came first, before the scope. The scope came before the carrier comparison. The photos were taken during the same visit as the measurements, not added later from memory. The code research happened before the climb. Reverse any of those and the supplement weakens. Try to add photos after tear-off and the conditions are gone. Try to build the scope from the carrier's numbers and the quantity gaps vanish. Order of operations is not a nicety here; it is the difference between a supplement that holds and one that collapses.

What pros get wrong

Even experienced crews leak money in predictable places. Watch for these.

Working off the carrier's measurements

If your quantities come from the carrier's estimate, you have already conceded the biggest category of supplement. Always have your own independent measurement report. It costs a little and it is the highest-return document in the process.

Treating code items as upgrades

Drip edge, ice barrier, and ventilation are constantly miscategorized as optional upgrades the homeowner can decline. Where code requires them and the policy carries ordinance-or-law coverage, they are required, not optional. Cite the section and stop calling them upgrades.

Skipping the undamaged slopes

Reps photograph the slope that looks hammered and skip the rest. Then the carrier approves a repair to two slopes and you cannot prove the others. Chalk a test square on every slope, every time, even the ones that look clean. Slope-by-slope documentation is what supports a full replacement versus a partial repair where the damage warrants it.

Vague photos with no scale and no context

A close-up of a hail bruise with nothing for scale and no indication of which slope it is on is nearly useless to a desk reviewer. Overview, detail, proof, every time. Chalk the hits. Put a tape in the frame for quantities.

Forgetting collateral and soft metals

The dents in the gutters, the AC fins, the mailbox, and the window screens corroborate the storm and its direction. Crews focused only on shingles leave this evidence on the table.

No tear-off documentation plan

The decking supplement is the most common second-round supplement, and it is also the easiest to lose. If nobody photographs the rotted deck before the new wood goes down, the supplement has no proof. Build the tear-off photo step into your production process so it happens every time, rather than only when someone remembers.

Confusing storm odds with damage proof

Storm models and hail maps point you at likely damage. They do not prove damage on a specific roof. The proof is always the physical documentation: the marked test square, the dented metals, the photographed conditions. Lead with the physical evidence and let the storm context support it, never the other way around.

Submitting the supplement before the loss is documented

There is a temptation, once a rep has signed a deal, to fire off a supplement quickly to look productive. A supplement submitted before the conditions are fully documented is worse than no supplement, because it teaches the carrier to expect thin asks from you. Submit when the package is complete and the conditions are proven, not when the clock feels like it is ticking. A slower, airtight supplement beats a fast, leaky one every time, and your approval rate is what builds your standing with carriers.

Letting the photos and the scope drift apart

A scope that lists thirty line items and a photo set that documents twelve of them is a credibility problem. The reviewer notices the eighteen items with no visual support and starts discounting the whole package. Keep the scope and the photo set aligned. If a line item is on the scope, there should be a photo, a measurement, or a code citation that backs it. If you cannot back it, either you have not finished documenting or the item does not belong. That discipline keeps every package you submit trustworthy.

Edge cases worth planning for

Layered roofs

Two or three layers change the tear-off line item and sometimes the decking situation underneath. Photograph the layers at a cut edge before tear-off. Multiple layers are a legitimate labor line item and they are easy to prove with one clear photo.

Discontinued or unavailable shingles

If the existing shingle is discontinued and a repair cannot reasonably match, that supports replacement of the affected slopes or roof rather than a spot repair, depending on the situation and the policy. Document the existing product and note its availability status.

Solar arrays

A roof with solar needs detach-and-reset by a qualified installer, which is a real and often significant line item. Document the array, the number of panels, and the fact that specialized labor is required. Do not let it be assumed away.

Steep and complex architecture

Turrets, multiple dormers, and very steep sections carry labor that a flat per-square number ignores. Photograph and measure these features specifically. The labor modifiers exist in the estimating platforms for a reason.

Recent prior repairs

If the roof shows mismatched patches or recent partial work, document it. It affects how damage and pre-loss condition are assessed and can complicate a claim if not addressed up front.

Low-slope and flat sections

A home with an attached low-slope porch or addition needs a different system on that section, with its own line items. Do not let a low-slope section get scoped as if it were the same shingle field as the steep sections.

A repeatable field checklist

Reduce all of it to a checklist your team runs every time. Consistency is what makes the supplement predictable.

Before you climb:

• Order the aerial measurement report
• Pull the local code edition and reroof requirements
• Review the storm context and roof-age range for the address
• Confirm the policy's coverage basics with the homeowner so you scope to the right standard

On the roof:

• Verify measurements against the report; note discrepancies
• Document pitch by slope and number of stories
• Chalk and photograph a test square on every slope with hit counts
• Photograph every penetration, wall flashing, and valley
• Photograph all soft-metal and ground collateral
• Note and photograph layers, sags, soft spots, and staining
• Check the attic if accessible

Building the scope:

• List every component with measured quantity and reason
• Break out all accessories the carrier tends to bundle
• Add steep and high labor where pitch and stories warrant
• Cite the code section for every code-driven item
• List detach-and-reset items
• Flag conditions to confirm at tear-off

The package:

• Measurement report plus verification notes
• Complete line-item scope
• Organized photo set by slope and component
• Code references with one-line justifications
• Tear-off confirmation list, pre-framed with the adjuster

At tear-off and after:

• Photograph decking and hidden conditions before covering
• Document any new unforeseen condition with overview, detail, proof
• Submit the supplement as a structured comparison to the carrier estimate

Staying inside your lane

A closing note on professionalism, because it protects your business. Your role is to document conditions accurately and produce a correct estimate of the work required. You do not handle the claim, you do not decide coverage, and you do not promise the homeowner any particular financial outcome. The insurer assesses coverage and the homeowner owns the claim and makes the decisions about it.

Keep your language clean. Talk about conditions, measurements, code requirements, and the cost to restore the roof correctly. Avoid promising what a carrier will or will not pay, and avoid framing the work around a deductible. A well-documented scope speaks for itself, and a contractor who stays disciplined about scope, documentation, and code is the contractor whose supplements get approved and whose reputation with carriers and homeowners holds up over time.

The roof tells the truth if you document it properly. Scope it like an estimator, photograph it like a desk reviewer will never see it any other way, tie every item to a measurement or a code section, and the supplement stops being a battle. It becomes paperwork.

FAQ

When exactly should I scope the roof for supplement, before or after the adjuster's visit?

Before. The most defensible supplements are built during your first inspection, when you can measure, photograph, and document every condition firsthand. By the time the carrier's estimate comes back, the evidence for many line items is harder or impossible to capture. Treat the adjuster meeting as the moment you confirm what you already documented, not the moment you start documenting.

What measurements do I actually need before the adjuster arrives?

Total roof area in squares, slope-by-slope area, pitch of every slope, number of stories, and linear footage of ridge, hip, valley, eave, and rake. A third-party aerial measurement report gives you most of this, and you verify the key numbers by hand. Nearly every line item in your scope is a function of one of those measurements, so accuracy here is what makes your quantities defensible.

Which line items do adjusters most often miss or bundle away?

Starter strip, ridge and hip cap counted separately from field shingles, drip edge, ice-and-water barrier, step and counter flashing, valley metal, pipe boots and vents, ventilation, detach-and-reset of solar or satellite, and steep and high labor charges. Build your own complete component scope so each of these is listed with a quantity and a reason rather than folded into the field shingle number.

How many photos do I need, and what makes a photo hold up in a desk review?

Shoot in three layers for every condition: an overview showing where it is, a detail showing the condition clearly, and a proof shot with scale or markup such as a chalked circle around hail hits or a tape measure across a quantity. Chalk a 10-by-10 test square on every slope with the hit count visible. Use a timestamped, geotagged camera or app, and keep the set organized by slope and component.

How do code upgrades become supplement line items?

When the carrier's policy includes ordinance-or-law coverage, code-required upgrades triggered by the reroof are owed. Common examples are ice barrier at eaves, drip edge at all edges, ventilation brought to minimum net free area, and decking re-fastening or replacement to current code. Identify the local code edition and cite the specific section next to each code-driven item. A citation turns a maybe into a requirement.

What is the difference between a supplement and padding an estimate?

A supplement captures the real, correct cost to restore the property to pre-loss condition when the original estimate fell short on quantities, missed line items, unforeseen conditions, or code-required upgrades. Every item is measured, photographed, or code-cited. Padding adds cost without a documented basis. The discipline that separates the two is building a complete, quantified scope you could defend to a cash customer before you ever compare it to the carrier estimate.

How do I handle decking damage I cannot see until tear-off?

Flag it at the first inspection and pre-frame it with the adjuster. Tell them you will likely find decking damage under the felt and will document it at tear-off. Then build a tear-off photo step into your production process so the rotted or soft decking is photographed with overview, detail, and proof shots before the new wood covers it. A decking supplement with clear pre-cover photos is routine; one with no photos has no basis.

Should I use the carrier's measurements to save time?

No. Working from the carrier's measurements concedes the largest category of supplement, which is quantity error. Always carry your own independent measurement report. When your quantities come from a third-party document, a dispute becomes a comparison of two documents rather than your word against the adjuster's, and the more detailed document usually prevails.

Where does roof-age and storm data fit into pre-adjuster scoping?

Knowing the roof-age range and the modeled storm exposure for a specific address before you climb tells you which code-driven items to look for and which slopes to scrutinize first. Age is a range rather than a manufacture date, and a storm model is odds rather than proof. You still confirm actual condition on the roof and document damage with chalked test squares and photos. The data focuses your inspection; the physical evidence proves it.

What language should I avoid so I stay professional and compliant?

Stick to documenting conditions and estimating the cost to restore the roof correctly. Avoid promising what a carrier will pay, avoid framing the work around a deductible, and do not present a storm model as proof of damage. Your role is to document and estimate; the insurer decides coverage and the homeowner owns the claim. Clean, condition-focused language keeps your supplements credible and your business protected.
